Followed discussion not traceable

I'd like to check back on the comments I make regarding sentences in the Portuguese lessons, and yet, when I hit the "followed" tab at the top of the discussion page, I see only discussions I have started myself (like this one) and comments I've made while studying other languages. When commenting, I always hit the button saying I'd like to follow the discussion.

Why is this happening? Is this a glitch through all languages, or maybe only in the Portuguese course?

Well, I make it so that there is a check mark and it says, "following discussion," like it does here for this one. As I said earlier, the ones that get lost are the ones related to lessons... if I start a thread myself, it does get stored in my followed tab. Anyway, I will try playing with your suggestion, and toggling the follow button a couple of times before closing the tab.
